NITED STATES JOHN BULLOCK, OF WILMINGTON, DELAWARE.

DUMPING-WAGON.

SPECIFICATION forming part Of Letters Patent No. 635,420, dated October24, 1899.

Application filed April 7, 1899. Serial No. 712.135. (N0 model.)

To all whom it may concern.-

Be it known that I, JOHN BULLOCK, a citizen of the United States,residing at Wilmington, county of New Castle, and State of Delaware,have invented a certain new and useful Improvement in Dumping-VVagons,of which the following is a specification.

My invention relates to a new and useful improvement in dumping-wagons,and especially to that class of wagons which are intended for thedelivery of coal, and has for.

its object to generally improve upon the construction of such wagons,removing all obstructions from the interior of the body thereof, so thatthe coal may freely flow therefrom, and to increase the height to whichthe body may be raised in awagon of given dimensions, and also toincrease the distance to which the rear end of the body may be carriedrelative to the running-gear, thereby greatly facilitating the deliveryof the coal.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a side elevation of a wagon made in accordance with myimprovement,the body beingin its normally-lowered position; Fig. 2, asimilar View showing the body raised to its highest point; Fig. 3,a sideelevation showing the body tipped at the greatest angle after beingraised; Fig. 4, a central longitudinal section of the wagon, showing therelative position of the operating mechanism when the body is lowered;Fig. 5, a bottom plan of the wagon; Fig. 6, a rear end view thereof, andFig. '7 a section on the line x as of Fig. 1.

In carrying out my invention as here embodied, A represents the frame ofthe wagon, which is suitably mounted upon the wheels B and O, and fromthe rear portion of this frame dependthe supports D, having pivotedthereto at E the lifting-bars F, there being one upon each side of thewagon. The upper ends of these bars are pivoted at G to theside of therails 11, and at these same points are also pivoted the operating-barsI,

the lower ends of which have journaled therein the rolls J, adapted totravel upon the incline tracks K, said tracks being preferably formed ofwood and bound with metal. The operating-bars are connected at theirlower ends by a cross-piece L,havin g attached thereto the pulleys-M,over which run the chains N.

One end of each of these chains is attached to the side rails of thewagon-frame at 0, their opposite ends being secured to the WindlassshaftP. By this arrangement it will be seen that when the Windlass-shaft isrevolved in the proper direction the chains will be coiled thereon,during which operation the operating-bars will be drawn inward, theirlower ends traveling up the incline tracks, thus elevatin g the body, aswill be readily understood. While the body is being thus elevated, itisprevented from upsetting by the stay-rods Q, the upper ends thereofbeing pivoted at Rto the front of the body, while their lower ends arepivoted to the clips S. These clips are adapted 'to slide upon the sidebars T, in which are formed holes U, in order that the clips may be heldin any adjustment upon these side bars by the passage of a suitable pinthrough a hole in each of the clips and in "one of the holes in its sidebar.

further increase the angle of the body until reaching the position shownin Fig. 3, which represents the greatest inclination at which the bodymay be set, being considerably greater than the angle possible to beattained in wagons of the same dimensions of the usual construction. TheWindlass-shaft P is operated through a train of gears consisting of thegear V, secured upon said shaft, meshing with the pinion \V, pivotedupon a stud X, said pinion being formed with or'secured to a gear Y,which latter in turn meshes with the pinion Z. This last-named pinion issecured upon the crank-shaft (1-, adapted to receive a suitable crank12, by which it may be revolved, and in so doing transmit motion to theWindlass-shaft P to bring about the operations before set forth.

A pawl d, meshing with the teeth of the pinion Z, prevents anyretrograde movement of the crank-shaft, so that when the body is beingelevated the operation may be suspended at any time without danger ofdownward movement thereof. hen it is desired to lower the body, the pawlis disengaged from the teeth of the pinion, and to prevent a too rapidrotation of the crank-shaft a brake e, pivoted at f, is forced againstthe outer portion of the crank-shaft or a disk thereon to retard thisrotation.

A suitable bracket g is secured to one of the side rails of thewagon-frame and serves as an outside bearing for the train of gearing,including the crank-shaft.

It is to be noted that by the construction here shown and described noobstruction is placed within the body of the wagon, and therefore thecoal will readily flow therefrom without being hindered in its passageto the chute or other point of delivery.

The rear end of the body is provided with an upper end-gate h, which ishinged at 1', so as to be swung downward, and beneath this gate arehinged the two smaller gates j, so as to swing outward. A chain l issecured to the upper end-gate at m and passes through the eyes a,terminating in hooks p, which are adapted to'en gage the edges of thelower bars, so that when these are swung open and thus acted upon theiroutward movement will be limited, thereby directing the flow of the coaltoward the center in passing from the body.

I am aware that wagon-bodies have been mounted so as to be elevated uponoperatingbars to which they were pivoted and that stays have beenutilized to hold such bodies in position, and I do not broadly lay claimto such a construction; but

WVhat I do claim is 1. A dumping-wagon consisting of a suitable framemounted upon wheels having supports depending therefrom, supporting-barspivoted to the last-named members, a body to which said bars are pivotedat the center thereof, operating-bars pivoted to the body at the samepoint as the last-named bars, rolls journaled in the lower ends of theoperatingbars, inclined tracks supported by the frame upon which saidrolls are adapted to run, a windlass-shaft, two chains attached thereto,pulleys attached to the operating-bars around which said chains pass,the opposite ends thereof being attached to the Wagon-frame, means forrevolving the Windlass-shaft whereby the body may be elevated, stay-rodspivoted to the front of the body, clips to which the lower ends of theserods are also pivoted, side bars upon which the clips are adapted toslide, said side bars and clips having holes therethrough for thepassage of pins to hold the stay-rods in adjustment whereby the body maybe swung to any desired angle within certain limits, as and for thepurpose set forth.

2. In combination, a wagon-frame suitably mounted upon wheels, a bodyadapted to be supported by said frame, support-bars pivoted to the frameand to the body at its center upon the lower edge thereof, whereby noobstruction is formed within the body, operating-rods pivoted at thesame point to the body, their outer ends having rolls journaled therein,inclined tracks upon which said rolls are adapted to run, means fordrawing these rolls inward and up said tracks, whereby the body iselevated, a stay-rod so pivoted to the body and frame as to produce aparallel movement with the support-bars, and means for adjusting saidrods, as specified. 3. In combination with the body of a wagon of thecharacter described, an end-gate h pivoted to the upper portion of therear end of the body so as to be swung downward, means for holding it inits closed position, two gates jhinged beneath the first-named gate andadapted to swing horizontally, and a chain secured at its center to thefirst-named gate and passed through suitable clips terminating in hooksadapted to engage the edges of the said gates j, as and for the purposeset forth.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

JOHN BULLOCK.
